Triangles
I mean, what ARE they?
Triangle are a polygon(shape) with tri(three)
Angles. Now does it make sense? Three sides, three angles.
Now to learn the Angles/Triangles!!!
Oh, this'll be FUN!
Straight angle
The..... Straight one
A straight angle is an angle that is ..... straight. It measure 180'.
Obtuse
The big buddy
Obtuse angles are angles that are more than 90' in any way. This means that it is MORE than a right angle, and it can also be a straight angle.
Obtuse triangles are
Obtuse triangles are a triangle with ONE obtuse angle. If you had more than one, you would need one more side, so it would be a quadrilateral. Here's another look.
Acute
The wee little baby
An acute angle is any angle that is LESS than 90 degrees. So sometimes it can be really small! Like, do you know how small 5' is?
An acute triangle is a triangle with ALL acute angles. No right. No obtuse. Or else it WOULD be right or obtuse! Her's another look.

Right
The serious one
A right angle is a angle that is EXACTLY 90'. If it is 89' or 91', it is not right. Talk about picky!
A right triangle is a triangle that has ONE right angle, or else it would be a quadrilateral with 4 sides. Take a another look.

Equilateral
The other picky one
A equilateral is a triangle with three even sides and the same angle as each angle. And we thought that right angles were picky!

Isosceles
The not-as-picky one
An Isosceles triangle is a triangle with 2 even sides. Two sides are the same length.

Scalene
Not very picky
